SPECIFICATION forming part of Letters Patent No. 392,153, dated October30. 1858,

Application filed February 2, 1888. Serial No. 262,750, (No model.)

To all whom it mag/concern:

Be it known that I, GEORGE W. HIooX, a citizen of the United States,residing at Flat Bock, county of Wayne, State of Michigan, have inventeda certain new and useful Improvement in Dampers for Blacksmiths Forges;

. and l declare the following to be a full, clear,

and exact description of the same, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification.

My invention relates to certain new and useful improvements in dampersfor blacksmiths7 forges, and has for its object to provide a noveldevice for regulating the blast admitted to the lire upon the forge, andalso in connection therewith novel means for shaking the same, so as toproperly clean the grate and keep it free for the more effectivecommunication of the air to the fuelbed.

My invention to this end consists of the construction, arrangement, andcombination of devices and appliances, as more fully hereinafterspecified, and'more particularly pointed out in the claims.

In the drawings forming a part of this application, Figure l is a vie'win perspective illustrating features of my invention, with parts brokenaway. Fig. 2 is a vertical section showing the damper mechanismsubstantially at right angles to that of its location in Fig. 1. Fig. 3is a side elevation.

carry out my invention as follows:-

A represents a bed to support the fuel upon the forge, constructed withan orifice at a for the admission of the blast from the bellows to thefire upon said bed.

B represents any suitable inclosing-casing adapted to house parts of myimproved damper mechanism.

B is an orifice in the casing,throngh which a bellows may communicateinto the interior of the housing, and thence through the orifice a tothe fuel upon the bed A. i

The sides of the casing B may conveniently be cast separate and soconstructed and arranged as to fit one to another. The base of thecasing I prefer to construct with a central supporting Vbar or plate,b,which may be held in place by means of bolts b and b2 at either end,said bolts extending upward through the bed-plate A and secured thereto.At either side of this supporting-plate may be located additionalplates, b3 and b,which, for convenience of access to the interior of thecasing, may be removable.

Beneath the orifice a in the bed A, l locate a damper, O,which mayconform to the shape of said orice, the said damper being preferablyrounded on its upper surface, as shown in Fig. l, to permit its freevibration for the purpose of shaking down the ashes and cinders from thefire upon the bed A. This damperis constructed with a shank, c, of anysuitable construction,provided wi th a vertically-slotted arm, d,withwhich is engaged avibrating spindie, D, journaled in the casing andextended to the exterior', as at D', to permit the engagement of ahandle or shaker therewith to vibrate the damper. brace the spindle, andso as to permit a vertical movement of the damper While the spin- Ythrough the base of the casing, which may be accomplished by means of alever, F, engaged with the lower end of said bar, as by a linknconnection, j". This lever is suitably ful,n crumed in a supporting-arm,Gr, as at g, the construction being such that by a proper movement ofsaid lever the adjusting-bar will be moved upward or downward,asdesired,there by carrying with it the damper, so as to open or closemore or less, as may be desired, the orifice a, through which air iscommunicated to the fuel-bed. In this manner the quantity of the blastcommunicated to the lire may be effectually controlled. This feature ofregu lating the blast forms one of the chief ele-v ments of myinvention,the accomplishment of which is of great desirability and utility. At thesame time the shaking of the grate is ade- The arm d is constructed toemy rco quately provided for by one and the same device, the shaking ofthe grate and the regulation of the draft neither oneinterfering withthe other.

For convenience of engaging the spindle D in place the adjacent side ofthe casing may be slotted from the top to admit the spindle to itsbearing, the orifice being closed again by a plate, b5, so as to preventthe escape of air. I prefer to make the casing in sections,so thatit maybe put in place or taken apart without disturbing the forge.

A damper so constructed is evidently simple, durable, and efficient forboth the purposes for which it is designed.

Vhat I claim as my invention isl. The combination,With a supporting-bed,A,constructed with an orifice, a, of the damper C, provided with aslotted extension, and a 1ock-shaft,D,inserted through said slottedextension, and upon which the damper is made verticallyadjustahle,substantially as set forth.

2. rlhe combination, with the supportingbed A, constructed with theorifice a, of the damper C, mounted upon a rocking spindle,D, saiddamper engaged with a reciprocatory adjusting-bar, E, substantially asdescribed.

3. The combination, with the supportingv bed A, constructed with anorifice, a, of a casing located beneath said bed,a rocking damperlocated beneath said orifice, and an adj ustingbar, E, engaged with saiddamper and provided with an operating-lever, said bar constructed with aslot,e, in which the damper has engagement with said bar, substantiallyas described.

4. The combination, with the supportingbed A, constructed with anorifice, a, of a damper,C,a shaft, D, for operating the damper, and arod, E, for vertically adjusting it, substantially as set forth.

In testimony whereof I sign this specification in the presence of twoWitnesses.
